A. SITUATION ANALYSIS
Description of the disaster
On 23 September 2017, the Vanuatu Meteorology & Geo-hazards Department (VMGD) increased the alert level for Monaro volcano on Ambae island, Penama province to Level 4: a moderate eruption state. A new volcanic cone has formed within one of the two crater lakes (Manaro Vui). This alert level indicates that flying rocks and volcanic gas will affect the Red Zone – a 6.5 km radius around the volcano crater. Villages located further from the volcano’s crater can expect volcanic hazards, including explosions and ash rain. There is also an increased likelihood that ash falls around the island, especially in villages exposed to the prevailing trade winds direction. As a result of the volcano’s increased activities, many of the island’s water sources have been contaminated through ash fall and acid rain. Acid rain has caused damage to food crops and contribute to food and livelihood insecurity for people living on the island. At this level of activity, the VMGD had advised that the volcano’s activity may increase or decrease at any time without warning.
South, West and North West Ambae experienced ash rain and smoke as a result of the increased Volcano activities. An estimated 5,500 people were initially affected, however loud explosion and further ash rain was experienced throughout the whole island and a decision was made for mass evacuation to nearby islands Maewo, Pentecost (Penama Province) and Santo (Sanma Province). This then meant that the whole island population of approximately 11,000 people (based on the 2009 Census data) was affected.
